The thioridazine metabolites 7-hydroxythioridazine (2a) and 7-hydroxysulforidazine (2b) were synthesized. Commercial 4-chloro-3-nitrophenylmethylsulfone was converted to the corresponding 4-thiol through an intermediate xanthate ester. Subsequent zinc metal reduction provided the 3-amino thiolate. This salt was condensed with chloroquinone to yield 7-hydroxy-2-methylsulfonylphenothiazine which was
合成了硫代哒嗪代谢物7-羟基硫代哒嗪(2a)和7-羟基磺胺嘧啶(2b)。通过中间体黄原酸酯将市售的4-氯-3-硝基苯基甲基砜转化为相应的4-硫醇。随后的锌金属还原得到3-氨基硫醇盐。该盐与氯醌缩合,得到7-羟基-2-甲基磺酰基吩噻嗪,然后将其保护为异丙醚。使用氢氧化钠用2-(2-氯乙基)-1-甲基哌啶进行N-烷基化,然后醚裂解,得到2b。所述Ñ烷基化然后还原用二异丁基氢化和解封,得到2a中。这些参考标准将有助于探索代谢形成的2a和2b在对硫代哒嗪的神经安定反应中的潜在作用。
